摘要:
1. A method for expanding a stenotic opening paranasal sinuses in a subject, comprising: setting a stenotic opening device comprising: a) an expandable portion adapted to expand from the unexpanded configuration to the expanded configuration, wherein in the unexpanded configuration the expandable portion has a size to allow its installation within the stenotic opening and b) a drive mechanism configured to expand the expandable portion of the unexpanded configuration to the expanded configuration for 4 hours or more, wherein the expanded configuration expands the stenosed otverstie.2. A method according to claim 1, characterized in that the device includes extraction of the stenotic opening at a certain time after the device is expanded to the expanded konfiguratsii.3. A method according to claim 1, characterized in that the sinuses is a frontal sinus, maxillary or sphenoid sinus pazuhu.4. A method according to claim 1, characterized in that the fixing device comprises within the stenosed otverstiya.5. A method according to claim 1, characterized in that the drive mechanism extends extensible part by means of at least one of the following: osmosis, a metal with a shape memory spring, swellable polymer, the thermal expansion of the gas, thermal expansion of the liquid, the gas generating chemical reaction and expansion of the material by phase perehoda.6. A method according to claim 1, characterized in that the drive mechanism extends through a portion of the expandable osmosa.7. A method according to claim 1, characterized in that it comprises delivering
